Hi, I've lost the keycode for my Ford transit 4000 RDS. The serial is M199831 and how do you input it... cheers for any help

Try code 5 9 5 8

Ford Code Entry Instructions

Once the unit has been turned on the display will show ' CODE - - - -'

Press preset [ 1 ] repeatedly for the first digit
Press preset [ 2 ] repeatedly for the second digit
Press preset [ 3 ] repeatedly for the third digit
Press preset [ 4 ] repeatedly for the third digit

To save the code press the [ 5 ] key to accept.
